Title: Manufacture of ascorbyl monophosphates
Inventor: DLUBALA ALAIN
IPC: A23L33/15
Filed: 1998-03-02
Abstract: A process for the manufacture of alkali metal and alkaline earth metal salts of L-ascorbic acid 2-monophosphate comprises reacting a L--ascorbic acid 2-polyphosphate under alkaline conditions with an alkali metal or alkaline earth metal salt of L-ascorbic acid in concentrated aqueous solution, the amounts of the L-ascorbic acid salt and the alkaline earth metal hydroxide used as the base being arranged such that pH value of the reaction medium is held in the range of about 8 to about 11 and a stepwise transfer of in each case one phosphate group from the polyphosphate to the L-ascorbic acid salt takes place until essentially the polyphosphate has been consumed and only L-ascorbic acid 2-monophosphate salt is present. Preferably, the L--ascorbic acid 2-polyphosphate is produced in situ and calcium hydroxide is used as the base. Independently of whether the L-ascorbic acid 2--polyphosphate is produced separately or in situ, sodium trimetaphosphate is preferably used as the phosphorylating agent. A further aspect of the present invention comprises spray drying the mixture obtained after completion of the reaction, cooling and dilution to a suitable viscosity. The product of the process according to the invention is suitable as an additive for human and animal foodstuffs; it is especially stable against oxidative and thermal degradation and has an especially high content of L-ascorbic acid monophosphate vis-à-vis polyphosphates and is accordingly primarily of use preferably for the nutritional enrichment of fish feed.

Title: Microprocessor controlled railway car accounting and communication system
Inventor: ENGLE THOMAS H
IPC: B61L15/00
Filed: 1998-04-30
Abstract: Apparatus by which a controlling information processing unit can communicate individually with subordinate information processing units which are connected sequentially along a pair of electrical conduction paths. The controlling unit assigns a unique address to each subordinate unit, which it uses later for communication with individual subordinate units. The controlling unit controls an electrical current in the pair of conduction paths. Each subordinate unit has a shunt path which has a current sensor and a switch, so the subordinate unit can open or close the path. All of the switches on the shunt paths are initially closed.      In each subordinate unit, the shunt current is measured, and a high value indicates that the shunt is closer to the controlling unit than any other subordinate unit which has a closed switch.  The subordinate unit then receives its address from the controlling unit, stores its address, and opens its switch. Opening the switch in any unit causes an increase in shunt current in the next unit, and the address assigning process is repeated for that unit.      Later, the controlling unit uses the addresses to command subordinate units individually.

Abstract: A carbohydrate-based library is described which comprises a plurality of distinct sugar-containing ligands each bound to a resolvable portion of a solid support. The library is constructed by a method that includes a glycosyl bond-forming step. Libraries of differing sizes can be prepared by the method of the present invention in which large numbers of distinct species are made substantially concurrently by the formation of glycosyl bonds among many types of participants. Moreover, an assay, which allows the substantial simultaneous screening of essentially all the members of the library, is described. The isolation of novel ligands of low-affinity is thus facilitated.
Patent CA-2254093-A1 (CA)
Inventor: SCHMID KARL
IPC: H04L29/08
Filed: 1998-03-11
Abstract: The invention relates to a method for preventing unauthorized access to operating information stored in functional units (SLMY, MUX, EG) of a communications facility, which information can be transmitted to said units for configuration purposes from a system management unit (SM) via data links. To this end a password corresponding to the access authorization is entered into the system management unit (SM). Every time the facility is started an address characterizing the system management unit (SM) is transmitted to at least one of the functional units (SLMY) of the facility. Said functional unit (SLMY) establishes a link with the system management unit (SM) by means of said address, after which the system management unit transmits the password to the functional unit (SLMY), which in turn transmits the password to all functional units (MUX, EG) it is able to reach. Every time a data link is established with functional units (SLMY, MUX, EG) the password is added to the data link information and checked by the functional unit concerned (SLMY, MUX, EG) to ascertain whether the password matches the password stored in said functional unit.

Inventor: KAMIYAMA TAKAO
IPC: F16L58/10
Filed: 1999-01-26
Abstract: A pipe lining method provides for precise cutting of a main pipe liner bag along a branch pipe opening using a cutter while preventing the inner wall of a branch pipe and the cutter from damages. After a cutting protection member is attached along the periphery of a branch pipe opening of a main pipe, the main pipe is lined using a main pipe liner bag. Then, a cutter of a cutting robot introduced into the main pipe is driven to cut away a portion of the main pipe liner bag covering a branch pipe opening. Since the cutting protection member functions as a guide for the cutter when cutting the portion of the main pipe liner bag covering the branch pipe opening as well as functions as a protection member for protecting the inner wall of the branch pipe, thereby making it possible to precisely cut the main pipe liner bag along the branch pipe opening using the cutter and to prevent the inner wall of the branch pipe and the cutter from damages.

Title: Method for transmitting vsb digital tv with carrier frequency near co-channel ntsc audio carrier frequency
Inventor: LIMBERG ALLEN LEROY
IPC: H04N5/44
Filed: 1999-01-28
Abstract: An N-level digitally encoded signal at a symbol rate f s substantially equal to three times the NTSC color subcarrier frequency, N being a plural integer, modulates a carrier signal of a frequency within a few hundred kilocycles of the NTSC  audio carrier, for transmission through a channel subject at times to the presence of a co-channel NTSC analog television signal. The modulation is suppressed-carrier amplitude-modulation generating first and second amplitude-modulation sidebands. Any portion of the amplitude-modulation sidebands extending outside the channel is suppressed in the transmitted signal, thereby making the first amplitude-modulation sideband a vestigial sideband providing an image for only a portion of the second amplitude-modulation sideband closer in frequency to the carrier signal. The amplitude responses of the vestigial sideband and the portion of the second amplitude-modulation sideband closer in frequency to the carrier signal are halved in the transmitted signal compared to the amplitude response of a remaining portion of the second amplitude-modulation sideband further in frequency from the carrier signal. A fixed-amplitude pilot signal of the same frequency as the suppressed carrier is included in the transmitted signal.

Abstract: Miniature circuit breaker apparatus is taught which includes side-by-side ganged cases where one of the ganged cases includes the main circuit breaker operating mechanism and contacts and where the other case includes an actuable micro-switch, which is interconnected with an indicating device for providing either a bell alarm function for the circuit breaker system or an auxiliary switch function for the circuit breaker system. The bell alarm function is provided by tying the rotatable axes of the trip mechanism of the main circuit breaker into the case of the secondary circuit breaker casing for movement of an auxiliary switch. Which auxiliary switch indicates trip function when the main circuit breaker contacts have been tripped opened, thus providing a bell alarm indication. The handles of the two circuit breaker cases are also tied together, so that when the circuit breaker mechanism of the first casing is opened, the handles of the second casing are moved in conjunction therewith to also actuate the auxiliary switch by separate mechanism to provide an auxiliary switch indication that the contacts of the main circuit breaker portion are opened. Common circuit breaker components are available for use in either case, but only those components are actually utilized for the function desired.

Title: A user interface device for managing complex object relationships
Inventor: STERLING DARREN S
IPC: G06F3/048
Filed: 1999-03-30
Abstract: A user-interface device for working with views of complex pictures employs iconic navigation aids called "beacon nodes." The invention is particularly suited to large complex schematic drawings that are useful to view at various zoom factors to selectively view details and also to see a larger portion for context. The difficulty of returning to one set of features after focusing on another set of features is addressed. The user defines groups of elements (called 'clans') for which a close-up view is desired to be defined. The interface allows such views or groups of elements to be named and associated with a beacon node. (The user may zoom out from a saved view or close-up of a group of objects and zoom in on another view. To return to the saved view or close-up, the user can zoom out.) The beacon node may always be visible by insuring it is not scaled below a certain size. The beacon nodes may be colored to help the user distinguish them. By selecting a beacon node, for example, by clicking on it using a mouse, the display frames the corresponding clan.

Filed: 1997-10-03
Abstract: In accordance with the present invention, a safety monitoring apparatus provides protection in the event of an alarm condition or failure in a patient care system. More particularly, the safety monitoring apparatus is an independent functional unit within a device such as an infusion pump unit (100) which provides single-fault protection in the event of an alarm condition or failure in the pump itself or in the primary control and monitoring means (110) of the pump (100). The safety monitor utilizes control and signal inputs and can detect fault conditions independently of the primary control and monitoring means (110) of the pump. Parameters which the safety monitoring apparatus may independently monitor in an infusion pump (100) include motor control, air-in-line, flow-stop detection, mechanism motion, pressure sensing, door position sensing, and total volume infused. If a fault condition is sensed, the safety monitor can notify the primary control means, independently shut down fluid delivery, or sequentially do both.
